PHP - Help With Session Variable
Hi
I am using very simple code. Here it is Code: [Select] <?php session_start(); $user = "guest"; $uid = "1"; echo $_SESSION['user']."<br />"; echo $_SESSION['uid']; ?> it displays this error Code: [Select] Notice: Undefined index: user in C:\wamp\www\DealDash\index.php on line 5 Notice: Undefined index: uid in C:\wamp\www\DealDash\index.php on line 6 how can I solve this problem? Help please Similar TutorialsMy login script stores the user's login name as $_SESSION[ 'name'] on login. For some unapparent reason, i'm getting errors stating that $user and $priv are undefined variables, though I've attempted to define $user as being equal to $_SESSION['name'], using $user to look up the the user's privilege level (stored as the su column ) in the SQL table, and then where the result of the sql query is $priv which is then evaluated in an if statement. I can't seem to figure out why this might not be working. The code I'm using:
<?php
session_start();
function verify() {
//verify that the user is logged in via the login page. Session_start has already been called.
if (!isset($_SESSION['loggedin'])) {
header('Location: /index.html');
exit;
}
//if user is logged in, we then lookup necessary privleges. $_SESSION['name'] was written with the login name upon login. Privleges // are written in db as a single-digit integer of of 0 for users, 1 for administrators, and 2 for special users.
$user === $_SESSION['name'];
//Connect to Databse
$link = mysqli_connect("127.0.0.1", "database user", "password", "database");
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
//SQL Statement to lookup privlege information.
if ($result = mysqli_query($link, "SELECT su FROM accounts WHERE username = $user", MYSQLI_STORE_RESULT)) {
//LOOP TO CYCLE THROUGH SQL RESULTS AND STORE Privlege information as vairable $priv.
while ($row = $result->fetch_assoc()) {
$priv === $row["su"];
}
}
// close SQL connection.
mysqli_close($link);
// Verify privleges and take action. Only a privlege of "1" is allowed to view this page. A privlege of "2" indicates special
//accounts used in other scripts that have certain indermediate additional functions, but are not trusted administrators.
if ($priv !== 1) {
echo $_SESSION['name'];
echo "you have privlege level of $priv";
echo "<br>";
echo 'Your account does not have the privleges necessary to view this page';
exit;
}
}
verify();
?>
Hello everyone, I can get Test 2 to successfully operate the if statement using a variable variable. But when I try the same method using a session variable (Test 1) the if statement is not executed. Please could you tell me why the if statement in Test 1 is not being executed? Code: [Select] <?php # TEST 1 $_SESSION[test_variable] = "abcd"; $session_variable_name = "_SESSION[test_variable]"; if ($$session_variable_name == "abcd") { echo "<br>line 373, abcd<br>"; } # TEST 2 $test_variable = "efgh"; $test_variable_name = "test_variable"; if ($$test_variable_name == "efgh") { echo "<br>line 379, efgh<br>"; } ?> Many thanks, Stu hi all , i am working on a script which is oop driven and i m not much familiar with it, i appericiate if someone can help me to solve this problem , so basicaly current script is only setting one session variable to true if user login $_SESSION['is_successful_login'] , here is my code <?php include('files/db.php'); class ajaxLoginModule { private $timeout = null; private $target_element = null; private $wait_text = null; private $form_element = null; private $wait_element = null; private $notify_element = null; function __construct() { include ('config.php'); $msql = new Db; $msql->connect(); $this->is_login(); } function get_config() { $this->set_ajax_config(); } function set_ajax_config() { $this->timeout = AJAX_TIMEOUT; $this->target_element = AJAX_TARGET_ELEMENT; $this->wait_text = AJAX_WAIT_TEXT; $this->wait_element = AJAX_WAIT_ELEMENT; $this->notify_element = AJAX_NOTIFY_ELEMENT; $this->form_element = AJAX_FORM_ELEMENT; } function initLogin($arg = array()) { $this->get_config(); $this->login_script(); } function initJquery() { return "<script type='text/javascript' src='files/jquery-1.3.2.min.js'></script>"; } function login_script() { include ('files/login_script.php'); } function is_login() { if(isset($_POST['username'])) { $username = $_POST['username']; $password = $_POST['password']; $strSQL = "SELECT * FROM ".USERS_TABLE_NAME."

Thanks Need help declaring some session variable guys. I have a login form where the member enters his 1. Pilot Callsign 2. Password I want to declare that Pilot Callsign as the session variable on authentication. Using that Pilot Callsign session variable, I will fetch data from the database relevant to his profile. I already have the whole login page coded along with the restricted access pages (not coded by me). Check this out 1. Page is coded like this and working PERFECTLY --- Code: [Select] <?php // *** Validate request to login to this site. if (!isset($_SESSION)) { session_start(); } $loginFormAction = $_SERVER['PHP_SELF']; if (isset($_GET['accesscheck'])) { $_SESSION['PrevUrl'] = $_GET['accesscheck']; } if (isset($_POST['pilot_callsign'])) { $loginUsername=$_POST['pilot_callsign']; $password=$_POST['password']; mysql_select_db($database_brn_system, $brn_system); $LoginRS__query=sprintf("SELECT pilot_callsign, password, staff_level, firstname FROM pilots WHERE activated = 1 AND pilot_callsign=%s AND password=%s", GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text")); $LoginRS = mysql_query($LoginRS__query, $brn_system) or die(mysql_error()); $loginFoundUser = mysql_num_rows($LoginRS); if ($loginFoundUser) { $loginStrGroup = mysql_result($LoginRS,0,'staff_level'); if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();} //declare two session variables and assign them $_SESSION['MM_Username'] = $loginUsername; $_SESSION['MM_UserGroup'] = $loginStrGroup; ?> --- 2. As you can see, there already is a session variable declared for Pilot Callsign But on the next page "Restricted Access Page", when I try to call this same Session Variable, it doesn't work. I tried doing this <?php echo $_SESSION['MM_Username'] ?> Moreover, I even tried to fetch data from the table like this - SELECT * FROM pilots WHERE pilot_callsign=$_SESSION['MM_Username'] Doesn't work I wonder whether someone can help me please. I'm using the script below to create a page whereby users are presented with a list of image folders they have created.

I've been working on this for days now, and I just can't find the solution. I just wondered whether someoen could perhaps have a look at this and let me know where I'm going wrong. Many thanks and regards Question about variable variables and using session variables for them. O.K. So if I have: $foo = 3; $_SESSION['bar'] = "foo"; $$_SESSION['bar'] should equal the value of $foo, however I can't get it to work. Can someone tell me what I am doing wrong..... is it formatting??? Thanks, Thomas Hi all - hoping somebody can see this clearer than me... Goal: to create a very simple shopping cart page that receives $_POST info and stores it as an array in a session variable so items will be displayed in cart on clients return to shopping cart page. Problem: I can get the array to display the first item that I add to the shopping cart but each susequest item just overwrites the first because it is using the same session variable name. How do I store the next product info in a DIFFERENT session variable and display it on the shopping cart page without writing over the first? I have two pages with products on them which need to submit orders to the shopping cart page. They use a simple form with these fields: <form method="post" action="cartaction.php"> <p> <input type="submit" name="submit" value="Buy" /> <input type="hidden" name="cartaction" value="add" /> <input type="hidden" name="item" value="coppercasserole" /> </p> </form> This is what I have so far on the cartaction page which can display the first product added to the cart: <?php //If form is submitted, call the function and save all data into the array $_SESSION['form'] if($_POST['submit'] == "Buy"){ setSessionVars(); } function setSessionVars() { if ( !isset($_SESSION['cart']) ) $_SESSION['cart'] = array(); $item = array(); foreach($_POST as $fieldname => $fieldvalue) { $item[$fieldname] = $fieldvalue; } $_SESSION['cart'] = $item; echo "<table> <tr> <td>" .'<img src="images/'.$item['item'].'.jpg"' . "<td/> <td>" . $item['item'] . "</td> <td>" . '<input type="text(30)" name="value" value="1" /> <input type="submit" name="puchasednum" value="Update This One Item" />' . "</td> </tr> </table>"; } ?> I am new to PHP and have hit a brick wall as to how to display each product array as a new session variable in the shopping cart. I would like to keep it as simple as possible as I am getting easily confused! Is there a way that I can increment the session variable with something like this: <?php //session counter $counter = count($_SESSION['cart']); if (($_POST['name'] !="")){ $counter = $counter + 1; $_SESSION['cart'][$counter] = array(); } ?> Or can I pass a field as a product ID and use this somehow to create a new session variable for each product or clear the post variables somehow? Any help would be much appreciated? Thanks Hi Guys,
Here is the code, once logged in using known credentials it should display the content "welcome..." but it doesn't, instead it is showing "you are not authorized..." as if the session['username']); isn't being taken?
<?php
ini_set('display_errors',1);
error_reporting(E_ALL);

I am using WAMP and have made sure the username and password is in the database correctly, how do i debug this?
the error reporting has been switched on but it doesn't help me
is the problem with:
<?php if (login_check($mysqli) == true) : ?>I am trying to follow this guide: http://www.wikihow.c...n-PHP-and-MySQL Please could i get some help on how to make the login "detect" the username from my MySQL database and display the username Thanks Attached Files login_success.php.jpg 14.31KB 0 downloads The $_SESSION['record_to_chage'] variable is set- I know this as I can echo it out. $openedfile = file("myfile.txt"); sort($openedfile); // foreach($openedfile as $key => $newpick) { echo "<a href=\"/editpage.php?request=$_SESSION['record_to_chgange']&newcat=$newpick\" target=\"_parent\">$newpick</a>"; echo "<br>"; } The Resulting error: Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in For the life of me I can not figure where I am going wrong. Going to get coffee and some fresh eyes. Cheers I have a session variable called $_SESSION['patchurl'] in a php file , if i get in to an else statement this session variable gets set and i go to http://yyy page. below is the snippet of the code
<?php
session_start();
?>
<?php
echo '<script type="text/javascript">' . "\n";
if(isset($_SESSION["Email"])){
echo 'window.location="http://www.xxx";';
}
else{
$_SESSION['patchurl'] = "true";
echo 'window.location="http://yyy";';
}
echo '</script>';?>
once the patchurl session variable is set i call a php file which sets an other session variable called $_SESSION["Email"]. now what happens is the $_SESSION['patchurl'] is gone and ONLY the $_SESSION["Email"] is accessible ...can i not set two session variables? why does creating a new session varible overwrites an other one even though they are called different ? am i doing something wrong ?
Edited by Ch0cu3r, 08 September 2014 - 01:05 PM. I am trying to define a session variable where I can save it and use it as the user surfs the site. I need the variable saved as $amano so I can use it in my select from/where statement and to echo within a table. This is a test trying to capture and define the variable and works, but I can't get the variable $amano into the session. If I am then I don't know how to display it. <?php> session_start(); $id = $_POST['amano']; $_SESSION['amano'] = '$amano'; echo "Pageviews = ". $_SESSION['amano']; // My effort to see what is happening. echo "<br />"; echo "AMA # = ". $_POST['amano']; // I have it just like I want it here. echo "<br />"; echo "Sessions AMA # = ".$_SESSION['amano']; ?> hi there, i'm trying to put a message in the footer of a page which welcomes a person who is logged in with his/her name, using sessions of course; when i place this: Code: [Select] $username = $_SESSION['valid_user']; in the footer before the echo: Code: [Select] echo "You are logged in as $username"; but the session is also needed before the footer to use the username for other things , such as -checking his credit- so if place in footer the footer shows name in browser but checking credit would not happen as the assignment is at the buttom. IF i place the assignment above at the top of the file: everything works for the user and checking credit ..etc...but the footer is not there... cud not put this any clearer..sorry...hope if someone cud help...thanks Currently I am adding the concept of "entitlements" to my website. In the past, my "article.php" script would simply look to the URL for which article was being requested and then load it. However now that I am also adding the concept of "premium content" for "paid members", I need a way to control who sees what. What I am wondering is - from a security standpoint - how much information I should load into the $_SESSION variable. For instance, right now when a user logs in, I think I just store the "memberID" and "FirstName" and possibly "Username". It would be more efficient when a Member logs in to also retrieve their "Membership Plan" and store that in the $_SESSION variable, so that as they browse my website, each page can simply grab $_SESSION['MembershipPlan'] and run that through a function that I need to build and then determine if the user gets to access said page. However, maybe it would be more secure to have it so when a user lands on page XYZ, I would look at their "memberID" and query the database to get their "MembershipPlan"? Any thoughts on each approach? Again, my main concern is *security*, but I also suppose this plays into "performance".
page.php <a href="cart.php?action=add&id=38"> cart.php session_start(); $cart = $_SESSION['cart']; $action = $_GET['action']; switch ($action) { case 'add': if ($cart) $cart =$cart. ','.$_GET['id']; else $cart = $_GET['id']; } $_SESSION['cart'] = $cart; echo $cart; output: Insted of one time it adds the id two times. It prints : 38,38. can pls suggest me what's problem in the code. Thank's in advance. The first page is used to submit data to second page (and also show errors if there are any with the data submitted). The second page should be retrieving the posted data and assigning that data to session should it need to refresh back to the first page to show errors. The session data is used to repopulate the form. Right now I'm typing test into the review_name variable and when the page redirects back to the form to display the error messages, that field is not populated with "test".

it returns the rating I selected in the form. I'm probably missing something obvious here. Is it good practice to put an oop object in session variable I have a form where users enter name, username, password etc. The values are posted to a MySQL table where I also have a field called 'ID' that auto increments. I want to store that ID in a SESSION variable that I can carry over to other pages. Need help in doing this please. Hey guys, please tell me why the session var $_SESSION['return_url'] is not carrying from test.php to login.php The two echos in this file work perfectly, so i know the session var is registered... test.php <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>SWG:ANH • Bringing PreCU back to life...</title> <link rel="shortcut icon" href="favicon.ico" /> <link rel="stylesheet" type="text/css" media="screen" href="theme/main.css" /> <?php session_start(); // This section will generate a var containing the current page URL. This will be used to allow the language script to redirect users back to the page they // were on, in the language they selected. It is registered as a session variuable that will change every time the page changes. function curPageURL() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";} $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } return $pageURL; } // Here we register the URL we grabbed earlier in the session var. $return_url = curPageURL(); $_SESSION['return_url'] = $return_url; echo $_SESSION['return_url']; echo $return_url; include 'lang/enus.php'; include 'menu.php'; ?> login.php <?php session_start(); echo $_SESSION['return_url'] ; include 'dbconnect.php'; $username = mysql_real_escape_string($_POST['username']); $password = mysql_real_escape_string($_POST['password']); $return_url = $_SESSION['return_url']; echo $return_url; $result = mysql_query("SELECT COUNT(*) FROM account WHERE Username='$username' and Pass='$password'") or die(mysql_error()); $result = mysql_fetch_row($result); $result = $result[0]; if($result == 1){ $_SESSION['username'] = $username; header("Location:".$return_url); } else { echo "Wrong Username or Password. Use the back button. If you think this message is incorrect, contact the webmaster."; } ?> I know its not carrying because the echo in login.php is not returning anything and the script cant execute the header function because it has nowhere to go! Ive narrowed it down to the session var not carrying. Hello i have problem in set session variables in .htaccess file. i have tried some codes which are belows but i did not effect in php info file. <IfModule mod_php5.c> php_value session.gc_maxlifetime 86400 php_value session.cache_expire 86400 </IfModule> please let me know if any one have solutions fot this Hey guys, been awhile since I have been here, but I hit a little issue in reading session data reliably every time. What I am doing is reading the variables and values from a rarurlencoded string. Then putting that into a session array to populate parts of a form and fill in some hidden fields. After the form posts every now and then, about 1 in 50 or so attempts, I have one (always the same one) that just vanishes. Anyone ever experience anything like this? |
